Additional information
Bound in one of the three volumes of architectural drawings by Carlo Fontana included in the Geographical Collections and acquired for George III by James Adam from the collection of Cardinal Albani. Drawing on four sheets with title on the verso, originally attached to some manuscript notes entitled 'Scandaglio della spesa a rinovar l'acquedotto reale dell' antica Acqua Alsietina, la quale e ora si chiama della Fiora' and dated 29 April 1692. The hydraulic works around Lake Bracciano represented in these drawings were also discussed by Fontana in his 'Utilissimo trattato dell'acque correnti [...] con una esatta notizia di tutto quello, ch'e_ stato operato intorno alla conduttura dell' Acqua di Bracciano' (1696). The third volume of this treatise refers to Fontana's visit to the lake in April 1691, when he measured the amount of water flowing into it from River Arrone and studied the system used to regulate its levels. According to Braham and Hager, these drawings 'were probably intended as illustrations in a book which Fontana hoped to publish, Il Libro della Toscana antica, con la narrativa della Condottura dell'Acqua Trajana a Civita Vecchia"."
